BinarySmoothing3d

Transforms a binary three-dimensional image into another binary image with respect to the real local mean of each voxel neighborhood.

Access to parameter description

This algorithm computes a binary smoothing using a specified window size.
It consists of a two step procedure: Note: the binary smoothing does not preserve the topology of objects.
